You knew it was coming...
...and here it is: The Wright Ad. Nope, not posting that repulsive video here. But I'll note that even a few conservatives on the comments thread are objecting to the ad.
But the question is, will John McCain denounce it? Will he call for it to be taken down and not broadcast? He'd better get on the stick and denounce it himself (and not send some flunky out with a half-hearted criticism like he usually does), or risk going down in history as a racist. Is he man enough to do it? Probably not.
